"White Graphene" can greatly improve the performance of ceramic materials
Scientists in the United States propose that the incorporation of nano-materials "white graphene" into ceramic materials can significantly increase the strength, toughness, and heat and radiation resistance of ceramic materials. It has the potential to be used in nuclear industries, aerospace and other high-performance composite materials. field. White graphene is an alias for hexagonal boron nitride. It is a member of the two-dimensional material family. The structure is similar to that of graphene. It is an ultra-thin plane composed of a hexagonal mesh, but unlike graphene, the atoms are different. It is not a carbon atom but a nitrogen atom and a boron atom. Scientists at Rice University in the US said that they analyzed the combination of white graphene and xonotlite in detail. Silicate is an aqueous calcium silicate crystal with a layered structure that can be used to produce ceramics and cement. Only one atom thick white graphene layer can be inserted horizontally between the layered structures of the xonotlite to form a strong sandwich structure. Simulated calculations show that the white graphene layer can release the force on the composite material, making it three times stronger than the xonotlite, and the stiffness, ie, the ability to resist elastic deformation, is about 25% higher. It is not as easy as ordinary ceramic materials. Cracked. In addition, the material's heat and radiation resistance are also significantly improved. Related papers were published in the Journal of Applied Materials and Interfaces of the American Chemical Society. The researchers said that this idea can be used to design new multifunctional composite materials, and other two-dimensional materials may also have similar effects.
